Question My pc won’t start up after an upgrade attempt...

Jun 26, 2020
Hi guys,

Last year I’ve build my first budget pc and everything was working fine.

Today I wanted to instal m2 ssd but because of bad access I removed two sticks RAM. Than I realised that I’m missing the screw to fix the ssd. After a failed attempt I’ve installed my Ram back on. When I started PC I heard one beep sound, fans started working but display didn’t. Mouse, keyboard, mouse pad didn’t light up, same with the small led at the front of the case (there is one fancy light installed in my case that still works).

I checked in google, read a lot of forum threads and I found that one beep indicates Memory refresh timer error. I tried to plug just one RAM (each of them) to check if something happened to them. Same thing. I don’t have access to any spare parts to eliminate which part is faulty. Any ideas what can be a problem?

PC parts:

-asrock B450M HDV
-Ryzen 5 3400G
-Corsair vengeance 2x8gb 3000mhz
-coolermaster masterwatt 500W 80+

I don’t have any dedicated GPU, wanted to buy it later on. Im using the Radeon Vega 11 apu.
